Physostegia virginiana
OBEDIENT PLANT
SKU: 710-020
Description
Physostegia virginiana (obedient plant, obedience, or false dragonhead) is native to North America, where it is distributed from eastern Canada to northern Mexico. Physostegia are known commonly as obedient plants because a flower pushed to one side will often stay in that position.
It is a rhizomatous perennial herb producing clumps of erect, stems 2 to 4 feet tall. It has long, dense spikes of lipped "snapdragon-like" flowers in the summer. It is a good plant for adding late-season flowers to a garden, and flowers last for many weeks. Plants grow well in the sun or shade, and is one of the limited perennials that bloom well despite full shade.
Type: Hardy perennial
Hardiness zones: 4-9
Height: 3', 36", 90 cm
Location: Does equally well in sun or shade
Seeds per pack: 20
Germination: Start these seeds indoors right away for best germination rates. Your planting container should have holes in the bottom for excess water to drain. Sow the seeds just under the surface of a seed-start mix, and water in. Leave them at room temperature for 4 weeks. This helps break the phytohormones which inhibit germination. They will not grow yet. Then a cooling period is required. Cover them with plastic and place in a fridge for 80 days. Be sure they stay moist. After the cold-moist stratification period they are then brought back to a cool room (15-18C, 59-68F) for them to germinate. Germination is generally 30-60 days after the warming period, though some can take longer.
